Properties of Electricity that moves only in one Direction

Have you already handled a torch or a flash light?

This is a tool used by anyone to allow them to check their surroundings during the dark night. 

If you are going to check the internal parts of your flash light then it is simply made out of bulb, battery and a switch. 

To explain how it works, when you switch the torch ON the electric current stored from the battery will immediately flow around the bulb making it light up.

Batteries contain an electric current which causes the electrons to move from the material. 

If your torch composes of two or more batteries then the current will flow from one end of the battery to another and through the bulb. 

The electric current circulates around the battery and bulb for a continuous period of time until either you switch the torch OFF or the battery has been completely drained out of energy.

The circulation of the current flowing from the batteries through the bulb is what they call as the “Electric Circuit”. 

Turning the switch ON completes the circuit because current can freely flow but as you turn the switch OFF the light goes out because the circuit has been broken.

There are two different properties of Electricity which are the AC (Alternating Current) and the DC (Direct Current). 

All batteries and any source of electricity composing of positive and negative polarities are categorized as Direct Current.

Alternating Currents are those electricity from your wall-outlets or from the main lines.
